How to build complex dynamic hierarchy view (1-n & n-1)?

Does anyone know how to create a complex dynamic hierarchy treeview with ASP.NE开发者_运维知识库T or Silverlight or any other technology that can be viewed on a SharePoint page?

We have records in our database connected to each other with keywords predecessor and successor. Now we want to have a visual overview of these records on the screen showing the hierarchy.

Example of what we want to create:

I have found many solutions for custom treeviews, charts, hierarchy views, .. but none of them could create our view dynamically.

EDIT: The boxes should be interactive and the sollution should support most common browser without installing software for the client. (If possible)

EDIT 2: The diagram will show all the courses (=box) for a training. Some courses are grouped in modules (=color) and for some courses, you have to succesfully passed one or more other courses.

Your help would be very appreciated.

As the relationships are interconnected these are not actually hierarchies. You want a directed graph with custom user controls for the nodes.

Try these (most are open source or free):

• Quickgraph
• Graph Sharp (Graph#)
• Node XL
• Microsoft Automatic Graph Layout
• GraphViz
